...

Aya confronts Melissa. "What was that all about," asks Aya.

"Your mitochondria needs time to develop," says Melissa. She then fleas backstage and Aya chases after her...

...

They're both backstage. "What's going on, Melissa," asks Aya.

"My name is Eve!" She then mutates into a beast and goes down the sewers.
